Study Notes
Environmental Science
- Environmental science focuses on understanding how the Earth works, our interactions with it, and how to address environmental problems to live sustainably.
Sustainability
- Meeting current needs without compromising future generations' ability to meet theirs.
Three Principles of Sustainability
- Solar Energy: The sun provides warmth and supports photosynthesis, crucial for life.
- Biodiversity: The variety of organisms, natural systems, and services they provide. Biodiversity provides services like air and water purification, climate regulation, and pollination.
- Chemical Cycling: The continuous movement of chemicals through the environment, including organisms. It enables the existence of air, water, soil, and life itself.
Natural Capital
- Refers to Earth's natural resources and services, essential for sustaining life.
Degradation of Natural Capital
- Depletion of natural resources faster than nature can replenish them.
- Pollution: Contamination of the environment with harmful substances.
- Point Sources: Pollution with identifiable sources (e.g., a factory smokestack).
- Nonpoint sources: Pollution from dispersed sources (e.g., agricultural runoff).
Tragedy of the Commons
- Overexploitation of shared resources due to individual self-interest, leading to depletion.
Property Rights
- Private Property: Owned and controlled by individuals.
- Common Property: Resources owned and managed by a community.
- Open-Access Property: Resources that are not owned and are freely available to anyone.
Solutions to Environmental Problems
- Scientific solutions are crucial, but implementation requires government regulations and enforcement.
Ecological Footprint
- The amount of land and water needed to support a person or a population's consumption and waste.
- Ecological Deficit: Occurs when a population's ecological footprint exceeds the biocapacity of its area.
IPAT Model
- Impact (I) = Population (P) x Affluence (A) x Technology (T)
- A model explaining environmental impact based on population size, consumption levels, and technology's environmental impact.
Causes of Environmental Problems
- Population Growth: Increasing population leads to higher resource consumption and waste generation.
- Unsustainable Resource Use: Excessive consumption of resources, often driven by affluence.
- Poverty: Lack of resources and opportunities forces people to exploit the environment for survival.
- Excluding Environmental Costs: Companies often do not pay for the environmental damage caused by their activities, leading to a lack of incentives for sustainable practices.
Environmental Worldviews
- Planetary Management: Humanity's ability to manage the Earth for our benefit, encouraging environmentally beneficial economic growth.
- Environmental Stewardship: Humanity's responsibility to care for and manage the Earth for our benefit, but with an emphasis on environmental conservation.
- Environmental Wisdom: Humanity's deep connection to nature and dependence on it. It emphasizes respecting nature and living in harmony with it.
Environmentally Sustainable Society
- Renewable Energy: Primarily using renewable energy sources, decreasing dependence on fossil fuels.
- Biodiversity Protection: Conserving biodiversity, including ecosystems and species, to maintain ecological services.
- Waste and Pollution Reduction: Minimizing waste production and pollution to prevent environmental damage.
